' This shingle -machine includes a suitable verand sill, composed of wood and respectively` marked 19-and 19' In the lower portion of this frame a metal track-bed, as 20, is suitably secured and comprisesv a horizontally disposed channel-beam set with the web toward the husk-frame. A section of track, as 21, is placed upon the upper surface of the top wall of this bed adjacent the free edge, and sections of the web of the bed are preferably cut away Fig. 8 is a view of theto reduce the weight of the structure,'and a f step-block, as 22,0r the like is preferably placed on the lower beam or sill 19 midway its length to support the ytrack-bed.

The carriage 15 is formed witha base 23,

composed of a single section of timber of extended length and preferably rectangular in cross-section, and on the under side of this base adjacent the ends suitable trucks, as 24, Figs. 5 and 6, are arranged with the axles 25 disposed transversely said surface and the wheels 26 substantially midway the width of the base in alinement with each other, so that the carriage will thereby be operatively supported on track 21. Upon this base is securely seated an upright iron frame 27, which consists of separated end pieces 28 and a top and bottom plate,(marked, respectively,29 and 30,) and which are conveniently secured at the ends to respective extremities of said Aend pieces by bolts or the like passed through the plates and through suitable lugs provided at thedesired points on the end pieces. These end pieces are rendered of plate metal, and each comprises a vertically-disposed stem 3l, having a horizontal foot-piece 32, projecting laterally from one edge at the lowei` end, and a bracket 33 at the upper end, projecting from the stem in the same direction as the foot, and at the outer extremity of said foot a downwardly-projecting heel, as 34, is arranged to engage the side of the carriage-base 23, and at the outer end of said bracket an upwardlyextending lug 34 is formed thereon, to which the top plate 29 is secured. These end pieces are connected at the inner ends of the bracket parts by a suitable horizontally-disposed distance-bolt, as 36, and the frame 27 is fastened to the carriage-base by suitable bolts passed through the bottom plate 30, with the heels 34 resting against the front side of said base relatively to the position taken by the Sawyer, as designated by the letter A in Fig. l, and this frame is rigidly secured to the base and firmly supported in position thereon by means of diagonally-disposed truss-rods, as 35, one of which is placed at each side edge of the frame. These rods are oppositely disposed relatively to each other and are each rendered of suitable length to reach from the top edge of bracket 33 of a respective end piece to and through the adjacent end portion of base 23, and each rod is formed with suitable screw-threads on each extremity adapted for the engagement of suitable nuts, as 35', at the upper end, by which the rod is securely locked to a laterally-projecting lug 37, formed on said bracket, and a nut, as 38, on the lower end beneath said base, by the adjustment of which the rod is drawn to the required tension to rigidly brace the frame. y

Along the front side of the beam of the track-frame an inverted angle-iron, serving as a track 39, is conveniently secured to said beam, with the downwardly-projecting web 39 lying beyond said side, and this track is rendered of suitable length to extend throughout the length of travel of the carriage and is adapted for the engagement therewith of suitable slides 40, which are secured to the top plate 29 of the carriage. These slides include upwardly-extending lugs, as 41, secured to the back edge of plate 29, so as to rest between said web 39 and beam 19 adjacent each end of said plate. These lugs are rendered of suitable height to slidingly engage the back side surface of web 39', and suitable angle-brackets, as 42, are secured to said top plate of the carriage to slidably engage the front side of said web.

The trucks 24, Figs. 5 and 6, each comprises a base-plate 43, which is substantially equal in width to the wid th of the bottom surface of the carriage-base and of considerable length and is formed with a suitable opening 44 for the truck-wheel 26. This opening is greater in width than the depth of the hub of said wheel and is located midway the width of the plate adjacent one end, and at each side of this opening suitable half-boxes 45 are formed on the bottom surface of the plate to adord bearing for the frame on the end `portions of an axle 25, lixedly secured in said wheel. At one side edge of this base-plate at the half-box is secured a downwardly-extending bracket 46, having an in wardly-projecti ng shelf 47 at the lower end formed with a rectangular pocket 48, open at the top and one end and adapted as the seat for a wooden bearing-block 49. This block is conveniently secured from end movement in the pocket by a removable L-shaped keeper 50, which is preferably disposed with the stem upon the under surface of said shelf and the foot portion projecting across the open end of said pocket, and this keeper is suitably fastened in place by adjustable set-bolts, as 51, which pass through suitable apertures in said stem and have screw-threaded engagement with the walls of apertures conveniently formed in the shelf and are of suitable length to project into the pocket thereof and serve as means to raise the bearing-block when desired to compensate for wear. As now considered the truck-wheel is adjusted laterally by means of a set-bolt 52, having screw-tln'eaded engagement in a suitable aperture formed transversely the bracket 46 concentric with the bearing for the axle of said wheel, and the end of this bolt normally engages the end of said axle, so that the wheel can be set over by turning the set-bolt. This truck is set with the long end of its base extending toward the adjacent end of the carriage-base and the bracket at the back of the carriage, with the bearing-block slidably engaging the surface of the top wall of the track-bed, and the end 0f the adjacent truss-rod 35 is preferably passed through a suitable aperture in said truck-base and the nul 38 thereon brought to bear upon a seat formed on said base-plate at right angles to said rod, whereby the trucks and carriage-frame are rigidly fastened together, and the truck is still further secured in position by suitable bolts, as 54, which are lOO passed vthrough apertures in its base-plate and corresponding apertures in the carriage-base.

ByA arranging the pocket 47 with one end wall open and providing a removable keeper, as`50, the bearing-blocks can be readily replaced when worn by simply removing the keeper, and this maybevdone without disturb- -ing the position ofvthe trucks when the car- 57', fixed to a bracket 58', secured to the base r of said carriage on the back side surface.

This mangle rack isrenderedf of ysuitable length to move carriage 15 reciprocatively the distance required-1n sawlng` shingles, and as now considered it comprises an open frame- 60, having suitable gear-teethl arranged internally to conveniently form a continuousrack composed of aplurality of sections or runs of teeth, as 58 and 59, which are laterally offset relatively to each other-and preferably arranged i-n different planes. As now considered, the track-section 58 extends along one side offframe 60 and about the ends thereof, while the/section 59y extends along the opposite side of said frame, and an endless guidegroove is suitably formed on the frame by providlng an outer guide 61 and an inner guide 62, the former' consisting of a continu- -ous rib-disposed at the-outer said edge of the rack-section 58 and the latter consisting of va rim of less diameterthan'the outer guide convenientlysecured in position parallel thereto; by suitable bars, as 63, secured tothe outer edge 'of said guides.

Thedriver for the mangle-rack includes an operatively-mounted spur-gear for each run or section of teeth, Fig. 4, as a wheel 64, adapted tomesh with the rack-section 59,andl

a pinion 65, ol less pitch diameter .than the lwheel and adapted to mesh with rack-section 58.y Asv now considered both of these spurgears are ixedlymounted on one end-portion of a horizontally-disposed drive-shaft 66, joursuitable fiange on the outer edge of the iperiphery, so that said guides will be embraced by said flange and the adjacent side face of the spur-pinion, and a suitable friction clutchpulley,I as 67 is mounted von drive-shaftv 66,

' 16 includesa suitable base composed of, sepandthe clutch mechanism of thisV pulleyv is operatively connectedV to a suitably-fulcrumed treadle, as 68, disposed at the position taken bythe sawyer, through the medium Vof a rotatably-mounted rod '69, extending valong the front edge of the baseof the track-frame, a suitable shifter'connectedto said rod and the clutch mechanism', and said rod is connected to the treadle by means of a laterally-projecting'arm 70, fixed to the rod and a link 71, ,pivoted to said arm and to one end of said treadle. 'Y ,In forming the mangle-rack 55 as now considered thdi'iferentsets of teeth arearranged in different planes, so that the pitch-lines -will be separated in conformity with the differenceA in thepitch radii of the drivers, as 64 and 65, which will thereby pass in and out of mesh with the teeth of respective sections without jarring, and the teeth at the ends of the sections 58 areI somewhat reduced in thickness at the points, so as to properly clear the teeth in pinion 65'as the rack passesv into and out of mesh with wheel 64. i

In the present embodiment the husk-frame arated side timbers72, disposed laterally .at one side of the track-frame opposite the mangle-rack and joinedat the innerends to the base of the track-frame'and connected at the opposite ends by a cross-timber 73. Upon this base suitable stands', as 74, are disposed to support-the journals, as 75,`of a saw-arbor 76, adapted to carryva suitable shinglesaw 77, and Isuitable stands 78 of less height than the former stands areI secured to said base to carry the journals of asaw -arbor lthis point, to which the shingles are trans-l IIO ferred for the purposeof presenting them' to the jointing-saw.

The shingle-blocks are securely held in the carriage 15 by means of feed-rollers, as 83 and 83', the former of which is journaled in suitable'bearings, as 84, secured to the lbaseplate 30 of the frame, while 'the latter is mounted in similar bearings, as 84', secured toa plate, as 85, which is suitably slidably mounted for vertical movement on a cross-bar 86, fixed to the free ends of a suitable carrier consisting of laterally-disposed arms 87 ,which are pivoted at their free ends to respective end pieces 27 of the carriage-frame'adjacent the top by suitable bolts, as 88. The plate 85 u is normally yieldingly held in depressed position by coiled springs, as 85', placed'at eachy end of the plate and confined beneath laterally-l projecting stops fixed to the carrier, and this ISO plate is formed with downWardly-extending iingers, as 89, along the lower edge, which curve over the feed-roller 83 and are adapted to assist in securing the shingle-block, and the base-plate 30 is formed with upwardlyeXtending fingers 90, which curve over the feed-roller 83. To one end of each of these rollers is iiXed a suitable ratchet-wheel, as 91, having the teeth unequally spaced, as in the ordinary ratchet-wheels for this purpose. These rollersl are operated simultaneously in opposite directions by means of suitable gravitypawls 92, which are pivotally connected to a vertic-ally-disposed lever 93, which is fulerumed on a suitable pivot 94, tiXedly mounted on the rear end piece 27. These pawls are connected to the lever at opposite sides of its fulcrum, and the free ends thereof rest upon respective ratchet-wheels 91, which are oppositely disposed, so that the lever when operated in one direction serves to turn the feedrollers in opposite directions, and when operrated in the opposite direction both of the pawls ride on the ratchets. These pawls each comprise a stem oi' suitable size having an enlarged head at the free end, which is formed with an inclined end surface, as 92', havinga suitable channel extending with the incline and adapted to slidably receive a substantially rectangular plate 92", which comprises the bill of the pawl and is formed with an elongated slot adapted to receive a clamping-bolt,

as 91, which has screw-threaded engagement in a suitable aperture in the head, whereby the bolt can be loosened to release the bill for adjustment.

The inclined surfaces on the pawls are oppositely disposed relatively to each other, so that the bills will be properly presented to respective ratchet-wheels to rotate the feedrollers in opposite directions, and the teeth on the ratchet-wheels are properly spaced to cause the pawls to act therewith to move respective feed-rollers a short and a long turn alternately, so that the shingle-bloek-will be properly set.

The lever 93 is operative by means of a cam, as 95, Fig. 10, properly disposed to lie in the path of movement of the upper end of the lever as the carriage travels, and a cam-roller 96 is conveniently journaled on the upper end of said lever so as to engage in the track in said cam. As now considered, this cam comprises asubstantially S-shaped plate 97, formed with a downwardly-extending rib 98 on the bottom surface, which is bent substantially midway its length to approximately a right angle, and a second rib 99 set parallel to one stem of the first rib and at suitable separation therefrom to leave a track between said ribs for the passage of the roller 96. This cam-plate is adjustably secured on the lower surface of a lhorizontally-disposed bracket 100, consisting wardly-eXtending continuation of rib 99, and this bracket-plate is suitably mounted on the beam of the track-frame, so as to project from the rear upper edge, with said rib 99' parallel to the line of travel ofthe carriage, by means of suitable lugs 101, secured to said plate and beam by bolts or the like, and the cam-plate is adjustably mounted on the bracket, with the parallel ribs at the position in which the lever lies when the carriage is resting in retracted position, by means of a pivot-bolt 102, disposed in a suitable aperture formed in the cam-plate adjacent the forward end theremc and back of rib 98 and in a correspondingalvierture in the bracket. This cam-plate is con- Veniently secured in adjusted position by means of a clamping-bolt 103, disposed in a suitable aperture in the bracket and passing through a segmental slot 1041, formed in said plate concentric with the pivot-bolt 102, whereby the cam-plate can be readily adjusted to vary the throw of the lever 93 by loosening the clamping-bolt and swinging the plate about the pivot-bolt.

The free end oi' the irame which carries the upper feed-roller 83l is raised and lowered through the medium of a horizontally-disposed lever 105, operably mounted on a suitable fulcrum-bolt 106, secured in a standard 107, fixed to the top plate 29 oi the carriage, and this lever is operatively connected to said frame byavertically-disposed rod 108, pivotally connected thereto and to the plate 85, and is conveniently operated by a foot-lever, as 109, pivotally mounted at the front o1 the machine and connected to said upper lever by a vertically-disposed rod 110, having a suitable link connection with the foot-lever, as a vchain and ring 110, which permits the red to swing freely as it travels with the carriage.

To the free end of the foot-lever 109 is secured one end of a suitable line 111, which extends upwardly and over a sheave in a block 112, fastened to the beam of the trackframe, and then downwardly to the base of the machine, and the clutch-shitting rod 69 is provided with a laterally-projecting stem having a loop 115 at the free end, through which the pendent end portion of this line passes freely, and at the end of the line asuitable bumper is secured, as a weight 116, which contacts said loop as the line is drawn by depressing said foot-lever to raise the upper feed-roll, and thereby simultaneously opel'- ates the shifting-rod, which frees the clutch in pulley 67 and renders the feed-works inactive.

In the present embodiment the manglc-raek is yieldingly supported by means o1 a spring 117, Fig. 12, which is seated on the carriage and engaged with the stem 56, and as now considered the spring comprises a iat bar oi resilient metal suitably fastened to the carriage by one end and rendered of suitable length to project forwardly and engage said IOO ITO

and thereby yieldingly support the mangle rack, and thus insure a smoother travel of the lmomo 5 stem at a vpoint substantiallymidway its length, so as to bear upwardly on" the stem,

rack 'about thedriver. i

The operationof thismachine will be readily understood from the foregoing description by those familiar with this class of shingle machinery; but, brieflystated, it is substantially as followsy Granted the application of power to drive the pulleys ofthe `machine the Sawyer'A takes `a position at point A, Fig., l, y

presses down on foot-lever 109 andplaces a j shingle-block between the feed-rollers and then allows the lever retract, so thatthel carrierhaving the upper feed-roller will close f by ygravity upon the block. `The feed-works ing the latterportion of the reverse action,

'are then started by throwing in the clutch in pulley 67, and the carriage advances toward saw 77, and the roller on lever 93 enters track in cam 95, andthe lever vis Ithereby actuatedduring primary advancing action of the carriage and Serves to retract the pawls 92 relatively to the teeth onrespectivel ratchet- Wheels. `As, the carriage is returning the cam-roller passes through the cam-track durand the lever 93 is thereby reversed and serves toadvance the pawls, and thereby operate the feed-rollers, to set the block in the ordinary and well-known manner. After the machine is once started, as above set forth, the operation continues uninterrupted untill the block is reduced to shingles, and during this period the savvyeris at liberty to transfer shingles from the receiving-table 81 to the movable table 82 for the purpose of presenting them to the jointing-saw 80.

By employing the mangle-rack in the feedworks, as heretofore described, the carriage is given a positive motion with a return speed considerably greater thany the feed, and the lspeed is gradually reduced land increased at each end of the travel as the segmental portions of the rack travel about the driver, and the carriage is thereby reversed Without any perceptible jerk or jar. Furthermore,` by forming the carriage with the truss-rods, as

, heretofore set forth, the structure is rendered rigid, and the end pieces are firmly braced against lateral strains.
